ABSTRACT:
There are disclosed methods and compositions for retarding the ambient temperature hardening of a phenolic resole resin alone or with an aggregate when such resin is contacted with a nitroalkane and a hardening agent such as lightburned magnesium oxide, an organic ester functional hardening agent, and mixtures of lightburned magnesium oxide and an organic ester functional hardening agent in an alkaline medium. There is also disclosed a hardener composition for phenolic resole resins wherein the hardener composition consists essentially of a solution of a nitroalkane in an organic ester functional hardening agent.
